Last change on this file since ac7be54 was d5419f7f, checked in by butler, 10 years ago

Fixed problem with mac vs pc positioning of tool panels for now -

opened ticket to completely rethink panels in mac vs pc

Added close button/activated close method for tool panels that did not

have it. Tool panels are now much more consistant.
